MyGo v0.5.5 returns ui.Element as a checked value handle instead of a
pointer. Migrated with `mygo migrate-ui`, then fixed what the codemod
leaves to review:
- Element nil checks become .Valid(); absent elements are ui.Element{}.
- Input handlers and paint callbacks run outside the build pass, where
elements expire and Context methods are inert: read IsDisabled into a
local during the build, keep a ui.Handle for Focus, use c.Services()
for clipboard access, create ui.Local state during the build.
- Add core.AutoFocus: v0.5.5 records an overlay's opener after its
content builds, so same-frame autofocus lost focus restore on close.
It focuses one frame later; cascader rows defer their focus likewise.
- core.OverlayLayer identifies build passes by the root element, not
c.Now(), which repeats across passes and under the Tester clock.
- Context menus survive the opening press counted as PressedOutside;
split button tooltip no longer reorders its open menu; disabled
menubar rows pass presses to the panel; Form defers blur-started
async checks so the growing message no longer moves Submit away
from the release; Combobox drops its disabled copy now that MyGo
blocks typing under a disabled wrapper (canary flipped to a guard).
- The Tester clock is virtual: tests use Advance/Now instead of
time.Sleep/time.Now and read element state inside the view. The web
mirror advances the clock to wall time before each frame and input.
- AGENTS.md and docs describe the value Element API and the new pin.
Snapshot goldens are darwin-only and were not re-verified here.

295 ShimmerText 文字扫光
用途
处理中的状态文字（如“思考中”）上有光扫过。
最小示例
thinking := true
view := func(c *ui.Context) {
core.Use(c, core.Settings{})
feedback.ShimmerText(c, "Thinking…", feedback.ShimmerTextOptions{Active: thinking})
}
ui.Render(view, 400, 300, 1)
签名：func ShimmerText(c *ui.Context, text string, opts ShimmerTextOptions) ui.Element
参数
ShimmerTextOptions
| 字段 | 类型 | 默认值 | 含义 |
|---|---|---|---|
| Active | bool | false | 扫光；否则为静态 TextMuted 文字。 |
text 为空时 panic。
状态
- 逐字由 TextMuted 渐亮到 Text，再回落；只在绘制时动画。
- 以状态角色朗读文字。
- 减少动画或未激活：静态文字。
事件
- 无。
键盘操作
- 无。
限制
- 扫光时文字保持单行。
